Siesta for Model Number shy56a05UC - FD 8405

Sink drain clogged up. While attempting to unclog, caused water to back up in dishwasher. (Perhaps it was running and door got shut in process and it started again.) It flooded. Got water out. After sink was unclogged, DW drain motor operates with door open. I read an answer you gave on forum: "The Bosch dishwasher has a moisture sensor, (flood sensor), in the bottom assembly that will shut off the units' ability to do anything but drain out. The drain pump will run as long as the moisture is sensed and nothing else will work on the unit until the moisture under there is dried up." I know that the water valve could be broken, but I would like to try and dry out any water still in base. Can you advise where the moisture sensor is? Is that the same as a "float switch"? I found this same situation described in the PDF troubleshooter mentioned in your forum on page d3 in this post: http://forum.appliancepartspros.com/dishwasher-repair/7123-bosch-dishwasher-troubleshoot-manual.html#post19321 (although this PDF is prior to my model). Could you give me the least invasive first steps for potentially removing water that could have resulted when I plunged the sink? I did see some of the enzymes I had tried to break up the drain clog in the DW, so I'm assuming I backed the water up into it. Thank you

Answer

Hello Siesta. Yes, it is the float switch in the bottom of the unit.
